checkAuth custom error/response handling

**Is your feature request related to a problem? Please describe.**
when i implement custom checkAuth as recommended by examples (https://cube.dev/docs/security#custom-authentication) i cannot access the response to create my own status code and message. all i can do is throw which forces a 500 (not accurate response code, should be 401 or 403)

**Describe the solution you'd like**
`checkAuth` to take in the response so that i may mutate response
i'd like to write something like below:
```
checkAuth: async (req, res) => {
const auth = req.headers.authorization;
if (!auth) {
res.status(401).send({ message: 'auth token not provided' });
return;
}

// Replace `region` and `userPoolId` with your own
const jwks = await fetch(
'https://cognito-idp.{region}.amazonaws.com/{userPoolId}/.well-known/jwks.json'
).then((r) => r.json());
const decoded = jwt.decode(auth, { complete: true });
const jwk = _.find(jwks.keys, (x) => x.kid === decoded.header.kid);
const pem = jwkToPem(jwk);

const token = jwt.verify(auth, pem);
if (!token) {
res.status(401).send({ message: 'unauthorized' });
return;
}
req.securityContext = token;
},
```

**Describe alternatives you've considered**
this could also be handled internally in `node_modules/@cubejs-backend/api-gateway/dist/src/gateway.js` > `wrapCheckAuth` but this doesn't allow for as much developer control
i.e.
```
if (req.securityContext && !req.authInfo) {
req.authInfo = req.securityContext;
} else if (req.authInfo) {
if (!warningShowed) {
this.logger('AuthInfo Deprecation', {
warning: (
'authInfo was renamed to securityContext, please migrate: ' +
'https://github.com/cube-js/cube.js/blob/master/DEPRECATION.md#checkauthmiddleware'
)
});

warningShowed = true;
}

req.securityContext = req.authInfo;
} else if (!req.authInfo || !req.securityContext) {
res.status(401).send('unauthorized');
}
```

also, wrapCheckAuth will still need to take in `res` for this
